Said cock C2 may be regulated so thatand waterproof, and the second or outer shell the full supply of air(apart from that passing or easement is in communication with thethrough cock C)maybe turned into easement source of air-supply to theapparatus, so that B and thus tend to extend it telescopically, the saidair-supply will assist the telescopic or connection maybe made, throughsaid cock C2, between the air in shells A and B, so as to enable theshell B to be indrawn over the easement A. The pipe D is carried to thesurface and provides an escape for the vitiated or surplus air in theeasement A and at the same time forms a protector for the pipe C. ln theeasement A are gages E and E', the former, E, for indicating thepressure of the water upon the apparatus and the latter, E, forindicating the pressure of air within the shell B.

ln the shell A is a dead-weight F, adapted to slide upon a rod F, heldby stanehions or pillars F2. Said weight F is adapted to be easilyshifted backward and forward, as may be required, by means of endlesswire or rope F3, ruiming around pulleys Fl on the end of the stanehions.Aflixed to the end of the shell B and passing through female screw ornut G', afxed to the shell A, is a screw-shaft G, and passing throughboth the shells or casements A and B and through respectivestuffing-boxes H2 and H3 thereon is a shaft or spindle Il, on the outerend of which is a screw or propeller H. The inner ends of the screw Gand propeller shaft or spindle Il pass through and have bearings in adiagonal stay J. The outer end of this diagonal stay J has soles J whichwork in guides J2 upon the shell A, and this diagonal stay J forms asteadying-piece and guide in the relative movements of the shells oreasements A and B. The inner ends of both the screw G and the shaft orspindle lil have square ends, on which will take a crank-handle, so thatthe requisite motion to propel the apparatus through the water backwardand forward may be given to the propeller Il' and so that the necessarymotion to extend or to indraw the shell or easement B over the shell oreasement A may be given to the screw G. An air-tight and waterproof doorB is provided in back end of the shell or easement A, so that, ifdesired, a communication maybe made between the interior of therespective easements A and 3 and so that the gland H3 and the bearingGiS may be lubricated and attended to as required.

lVhere necessary in the shell or easement A, and particularly in thefront end, are ports or light-holes, those illustrated being` marked K,one above and one below the gripping or lifting appliances.

The lifting and operating appliances consist of an outer pipe or castingL, and it has a ball L seated exteriorly on the end of the nozzle-pieceL2 and retained in such position by means of the pressure of the waterupon an india-rubber envelop L3 pressing upon said casing L andprevented from actual contact therewith by conical spring L4, butforming a practically air-tight and waterproof joint around said casingor pipe L. In the ends, both inner and outer, of said casing L arestuffing-boxes or glands L5, taking around a pipe or outer handle M',surrounding rodhandle M.

The outer end of said pi pe-handle M terminates in a female thread ornut M2, through which passes the screwed end of the rod M. The inner endof said outer handle M terminates in stuffing-box or gland or otherair-tight joint Ms and the operating-handle M4, while the rod Mterminates in an operating-handle M5. On the outer end of the femalethread or nut M2 are jointed the claws N, which may be of any desiredshape and capacity. Passing through slot-s in said claws N are the endsMj of T-piece on the outer end of rod or handle M. New by themanipulation of the two handles M'1 and M5 and the flexibility of theindia-rubber cone L3 and spring LA1 the claws N maybe operated to pickup anything within reach of their length. Said claws il are drawntogether and parted from one another by the revolution of the rod M inthe female screw or nut M2, as is easily understood, extendingorindrawing the end M of the rod M between the said claws N.

In operation the workers enter the casement A through door A2, which isthen tightly fastened on top of dome or chest A. Then to sink theapparatus they open connection by three-way cock C2 between theeasements A and B and then revolve screw G, so that the easement B willtelescopically close upon easement A and reduce the displacement of theapparatus. \Vhen the weight overcomes thedisplacement,theapparatussinks. `\Vhen on the bottom or upon any wreckage or submarineworkings, the operator regulates the set or inclination of the apparatusby manipulating the endless cord F3, so as to place the dead-weight F insuch position as required. To regulate the quantity and pressure of theair-supply in the easement, the cock C is handled to requirements. Topick up pearl-shell or other objects, the handles M4 and M5 are operatedas before described and the products or holdings of the claws N arereleased over a basket or receptacle (not shown) which depends from theoverhead or above water working station. To move the apparatus backwardor forward, the spindle Il is revolved by crank-handle and the propellerIl causes the desired alteration of position. To rise to the surface,the cock C2 makes connection of air-supply pipe C with interior ofeasement l5 and the screw G is revolved to extend the shell or easementB, and when the displacement becomes in excess of the weight theapparatus rises to the surface when the workers are released throughdoor or cover A2.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim isl. In diving apparatus of the class set forth thecombination with a shell or easement containing the operators, of asecond and telescopic outer shell or easement adapted to airtightlyslide upon said first shell or easement IOO IOS

so as to reduce, or increase as the case may be, the displacement of theapparatus, substantially as herein described and explained.

2. In diving apparatus of the class set forth the combination Withashell or easement containing the operators, and having ports or lightstherein, of aball-jointed casing forrods or handles, of claws or grippersitting upon a nozzle-piece and held in place by a flexible cone,substantially as herein described and explained.

3. In diving apparatus of the class set forth, the combination of thetelescopic shells or easements A B, the threaded shaft G passing througha nut G fixed in one end of the shell A and journaled in abearing fixedin the end of the shell B, a spindle H journaled in bearings in the endsof said shells and' in a diagonal stay J, and guides J2 in which saiddiagonal stay is movably seated, substantially as shown and described.

Dated this 8th day of September, 1896.
